CUTCOMP

[red987]

Ok so I'm getting frustrated with NX. I have two post files that need a little tweaking. Something that would seem easy, but apparently not so much. Ok so when posting multiple operations with cutter comp in one program file. I get a different result from each post processor. The first one cancels cutter comp after each operation. No problem accept it doesn't include a dia offset for any of the remaining operations.

The second is much worse. not only does it not include the dia offset for any of the remaining operations. It also ignores the lead in for the current operation and instead sends the tool (at cut depth) directly to the very first lead in location. no matter what is in the way. (Catastrophe ensues) I'm ready to beat my head on the wall here.

Does anyone have a clue what I can do to fix it?

Have you tried creating a new post in Post Builder, and comparing the results?
If that output is what you want, you can compare your posts to the new one.

In your first case, you probably need to force out the D inthe G41 block in PB.
For the second, I would have to look deeper.

If you don't get help here, there are lots of post experts in the Siemens PLM NX Manufacturing Discussion Forum.

There is also a series of tech tips videos on Post Builer, if you are new to that.

the diamter offset should be modal on the machine?

We force the D and the G_plane (G17 G18 G19)
Many times we may stop and have the operator check a dimension and then update the Dia comp to adjust.

If the D is not called out again then the new value does not get read in the control.

D is modal but as Joycejo stated we may have to stop mid program so it needs to be there... ill see about the force part in the first, but the second is the real issue. Thanks for the replies I may repost in the other forum just to see it they have any ideas..

Still nothing on the extra move. here or the other forum.. got to out put of the first working not just that pesky move to the original location....
